Default Re: Headlight bulbs

You don't focus them,but you DO have to aim them.Not the same thing.Here they're riding the inspection stations pretty hard on using the aiming machine.The garages that I know of are using the machine made by Symtech.They have found the $1000.machine isn't great,but the $1300.one works well.It's pretty interesting to watch.You set the machine in front of the car,and adjust it so it picks up some reference points to go by.The guys I watch use the tops of the wheel rims to establish a level.Once all the levels,heights and distances are established you can aim the lights.It would take pages to explain,but the Symtech manuals are online and explain how they work.You really can NOT aim LED lights at the wall and adjust them.The machine sees those blinding concentrations of light that won't show up on a wall.You can change the aim of the headlights without seeing any change by eye standing there,but you can see the shape of the light being thrown in the machine.
